    • A liquid crystal display capable of improving a color reproduction range is disclosed. The liquid crystal display includes a liquid crystal panel having a plurality of gate lines and a plurality of data lines which cross each other to define a plurality of unit pixel regions; a first pixel region having a first dot pitch among individual pixel regions in at least one of the unit pixel regions; and a second pixel region having a second dot pitch among the individual pixel regions in the unit pixel regions, wherein the first and second dot pitches of the first and second pixel regions are different from each other. By this configuration, the pixel electrodes are formed to have the same opening ratio in the individual pixel regions forming a unit pixel by changing the shape and size of the pixel electrodes in a region having a sensor and a region without a sensor, thereby improving a color reproduction range and improving the display quality of the liquid crystal display.

    • An optical pickup apparatus is capable of recording data in and/or reproducing data from recording mediums with different formats by using one single optical system. The optical pickup apparatus includes an optical system, wherein a filtering surface that transmits or reflects wavelengths from different rays coats the peripheral portion of the center portion of an input surface and the peripheral portion of the center of an output surface. A transmitting surface having a conical shape is disposed in a central portion of the input surface and projected inwardly or outwardly with respect to the input surface. Therefore, the optical pickup apparatus can be applied to different recording mediums using rays having different wavelengths and a lightweight, small optical pickup apparatus can be implemented by using one single optical system.
